When a family includes a child or adult with a disability, careful estate planning is essential. It ensures long-term security for that person while balancing the needs of other family members. One option often considered is a Disabled Person's Trust — in simple terms, a trust for someone who meets the statutory definition of a "disabled person", with special tax rules designed to support their future needs.
A common question is whether to set up the trust during one's lifetime or only through a Will. Both approaches can work well, but the right choice depends on the family's objectives, financial position, and the beneficiary's circumstances.
What Is a Disabled Person's Trust?
A Disabled Person's Trust is a trust that meets the conditions in section 89 of the Inheritance Tax Act 1984. Where these conditions apply, the trust benefits from favourable inheritance tax treatment compared to an ordinary discretionary trust.
To qualify, the beneficiary must meet the definition of a "disabled person" under the relevant legislation — which encompasses people who lack mental capacity within the meaning of the Mental Capacity Act 2005, or who are in receipt of certain disability-related benefits. A specialist adviser can confirm whether a particular beneficiary qualifies.
These trusts are often used to:
- Protect funds where the beneficiary may be vulnerable or lack capacity
- Provide lifelong support without giving an outright inheritance
- Manage how funds interact with means-tested benefits
- Ensure assets are held and invested for the long term under trustee oversight
Setting Up a Trust During Your Lifetime
A parent or family member can create a Disabled Person's Trust during their lifetime and transfer assets into it. This could be a substantial initial fund or a nominal amount with the intention of adding more later — including through a Will on death.
Reserved legal activity
Drafting a Lifetime Disabled Person's Trust is a reserved legal activity under the Legal Services Act 2007. It must be prepared by a qualified and authorised professional — not a DIY document.
Key advantages
Advantages of a Lifetime Trust
- IHT planning can start earlier — a lifetime transfer may qualify as a Potentially Exempt Transfer (PET), falling outside the estate if the donor survives seven years
- Immediate protection — trustees can fund therapies, equipment, specialist care, or accessible transport right away
- Governance can be tested while you're alive — you can see how trustees operate and whether processes are robust, with amendments still possible
- Acts as a central "container" — other relatives can contribute during their lifetimes or through their own wills, promoting consistent investment and decision-making
Potential drawbacks
- Reduced flexibility — once assets are transferred, they are no longer yours; a serious consideration if you may need them for retirement or care costs
- Ongoing administration — trustee decisions, record keeping, annual tax returns, and Trust Registration Service compliance all require real effort
- Care fees scrutiny — lifetime gifting may be examined under Care Act 2014 principles on deliberate deprivation of assets if you later need local authority-funded care
- Higher upfront cost — creating a lifetime trust is generally more expensive than including equivalent provisions in a Will
Creating a Disabled Person's Trust by Will
Alternatively, the trust can be created by will so that it only comes into effect on death. The Will directs that some or all of the estate passes into the trust rather than to the disabled person outright — keeping full control in the client's hands until then.
Key advantages
Advantages of a Will Trust
- Full control during life — you retain complete flexibility and financial security while keeping options open if circumstances change
- Simpler to maintain — no trust administration until death, which suits families where simplicity and cost-effectiveness take priority over immediate IHT mitigation
- Easy to update — if the disabled beneficiary's health, benefits position, or capacity changes, the Will can be amended without unwinding a lifetime structure
Potential drawbacks
- No lifetime IHT reduction — assets remain in the estate until death, so this route cannot begin the seven-year planning clock
- Delayed access to funds — the trust is usually funded only after probate and estate administration, which may cause a gap if the beneficiary needs urgent financial support
Conclusion: Which Approach Is Right?
A Disabled Person's Trust can provide long-term security and valuable flexibility — but there is no one-size-fits-all answer. The right structure depends on your family's financial position, the beneficiary's current and future needs, and how much control you want to retain during your lifetime.
Lifetime trust vs Will trust — at a glance
A lifetime trust offers earlier tax planning and immediate support, but involves giving up control and accepting ongoing administration costs and responsibilities.
A will trust preserves simplicity and flexibility during life but does not reduce inheritance tax exposure and may delay access to funds after death.
In some cases, a blended approach works well — for example, creating a modest lifetime trust now, with family members adding further funds through their own wills. The best solution will depend on the full picture of the family's financial position and the beneficiary's needs, and should always be developed with specialist legal and financial advice.
Disabled Persons Trusts involve complex interactions between inheritance tax, income tax, capital gains tax, means-tested benefits, and care funding rules.
